This is the first and last "clothes" thread I am going to read
but SURELY there is far better outdoor clothing on the market today??
What about a decent Polartec fleece. The best one is under £100, 1/3 of the cost of a leather jacket from a pilot shop, and far warmer. They come in three grades, 100, 200 and 300. A #200 is OK for most of the year and a #300 is fine for freezing temperatures with just a T-shirt underneath. There are also extra-windproof versions.
This is what all serious outdoor people wear. The stuff is light and ultra breathable and with Goretex or whatever on the outside, 100% waterproof. It can be expensive but isn't as bad as the leather jackets from Transair. Outdoor clothing has undergone a huge revolution in the last 5 years. I used to have leather gear (in motorbike days and since) and chucked it all out, together with pullovers, sweaters, all that sort of stuff.
There are Polartec gloves too. It's the biz and one can live in it all year round
